Neural Network: Out of memory. Type HELP MEMORY for your options.

I have a net object which was trained on my slower machine and worked perfectly. My old machine was a 64 bit windows 7, 32bit matlab and 3 gb of ram. but on my new machine which is way more powerful i run into memory problems using the same script and training data.

The config of my new machine is as shown below. Running windows 7 64-bit version and matlab 2013a 64 bit version. Memory details below:

>> memory

Maximum possible array: 11414 MB (1.197e+10 bytes) *

Memory available for all arrays: 11414 MB (1.197e+10 bytes) *

Memory used by MATLAB: 1222 MB (1.281e+09 bytes)

Physical Memory (RAM): 7759 MB (8.136e+09 bytes)

• Limited by System Memory (physical + swap file) available.

Size of my training data:

>> whos

Name                    Size                  Bytes  Clas
nn_input              126x62500            63000000  double               
nn_output             126x4                    4032  double

So, as far as memory is concerned my machine should support it. (It worked on my slower machine so clearly memory should not be a issue).

Even using the same trained net object trained on my slower machine results in: Out of memory. Type HELP MEMORY for your options.

Error in nnMex2.codeHints (line 117)

hints.TEMP = zeros(1,ceil(tempSize/8),'double');

Error in nncalc.setup2 (line 13) calcHints = calcMode.codeHints(calcHints);

Error in network/sim (line 321)

[calcLib,calcNet] = 
nncalc.setup2(calcMode,calcNet,calcData,calcHints,isParallel);

Error in network/subsref (line 17)

     otherwise, v = sim(vin,subs{:});

in my new machine. And when i start to train using the toolbox, my computer just hangs or MATLAB starts complaining OUT OF MEMORY.

What could be the possible problem?

is the error about OutofMemory:java heap Space ?

[Anthony Shivakumar]

no, it just states "Out of Memory"

Sorry, then i have no idea!
